Flyer for textile machines



June 17, 1958 F. RIDGwAY FLYER FOR TEXTILE MACHINES Filed Nov. 1s, 1954 United States Patent() FLYER FOR TEXTILE MACHINES Frank Ridgway, Stockport, England, assignor to Arundel, Coulthard & Company Limited, Stockport, England, a British company Application November 18, 1954, Serial No. 469,698

Claims priority, application Great Britain February 17, 1954 This invention has for its object to provide an improved construction of flyer with renewable and self threading yarn guide for use particularly in machines for the uptwisting of yarn from double flanged bobbins.

The invention consists in a ilyer particularly for use in machines for the uptwisting of yarn from double anged bobbins comprising a metal cap having a rolled over edge, which revolves co-axially around the upper ange of the bobbin, characterised in that a renewable and self threading yarn guide is located in a cut-away portion of said rolled edge, saidv guide being made of wire with its ends pointing in opposite directions and with a double hair pin bend in planes at right angles to one another located between such ends but nearer to one end than the other. The longer end is rst forced into the hole at one side of the cut away portion when the shorter end can be pressed into said cut away portion, the guide being then moved to bring the double hair pin bend into the cut away portion, with the open side of the guide facing the desired direction to give the guide self threading properties.

The invention further comprises a flyer as aforesaid which revolves a disc resting upon friction material on the top of the double flanged bobbin.

Referring to the accompanying explanatory drawings:

Figure 1 is a sectional view of a double flanged bobbin on a spindle with a flyer having a yarn guide therein constructed and arranged in accordance with this invention. Figure 2 is a plan View of Figure 1.

Figures 3 and 4 are detail views drawn to a larger scale than Figures 1 and 2 showing the yarn guide in its running position, Figure 3 being a side View and Figure 4 a plan view.

Figure 5 is a side View and Figure 6 a plan view showing the guide in process of being removed from or inserted into theilyer.

In Figure 1, the double flanged bobbin a is mounted to revolve with a spindle b in the known manner and a iiyer c in the form of a metal cap with a rolled over edge d has a centre spindle e secured thereto which is supported by a ball f carried in the upper end of the spindle b in the usual manner.

The rolled over edge d of the cap c has a cut away portion at g, leaving a hole into the roll at each side ICC of the cut. A yarn guide h made of wire with its ends pointing in opposite directions and with a double hair pin bend in planes at right angles to one another between such ends but nearer to one end than the other is adapted to be inserted into the roll d at its cut away portion.

As shown in Figure 5, the long end i of the wire guide h is irst inserted in the roll at one side of the cut away portion, after which the shorter end j of the Wire guide can be sprung into the roll at the other side of the cut away portion. The running or service positions of the guide are shown in Figures 3 and 4, where the double hair pin bend comes into the cut away portion g of the roll d. To remove the guide from the roll, a reverse series of movements is performed. The guide is moved to the full line position in Figure 6, when its shorter end j is sprung outwards and pulled to draw the longer end i out of the roll.

The double bend formation of the wire h provides an effective yarn guide and the open side of the guide is arranged to face the desired direction according to whether the flyer travels clockwise or anti-clockwise, so that the guide is self threading. It can be readily removed and a new guide inserted.

To control the amount of resistance to the rotation of the flyer c, a steel disc k loosely mounted around the fitting m, into which the spindle e of the flyer projects, is driven by a pin n through a hole in the cap and rests on a felt or other type of friction material o between the disc and the top of the bobbin a. Greater resistance can be obtained by increasing the weight of the disc k.

What I claim is:

1. A yer particularly for use in machines for the uptwisting of yarn from double flanged bobbins, comprising a metal cap having a rolled over edge with a peripheral gap therein, which revolves co-aXially around the upper flange of the bobbin, a guide made of wire with its ends pointing in opposite directions and with a double hair pin bend in planes at right angles to one another located between such ends but nearer to one end than the other, the ends of the guide projecting into the rolled over edge of the cap, the open side of the guide facing the desired direction to give the guide self threading properties.

2. A yer with renewable and self threading yarn guide in a cut away portion of the rim thereof as claimed in claim 1, further characterised in that a disc beneath the cap is revolved by the latter, a pad of friction material resting on the top of the double anged bobbin with the disc resting on the pad to control the resistance to the rotation of the ilyer by the yarn in the guide.
